Intratracheal Cathether

Product Details

Solution Based Design

BLEScath® is indicated for the administration of pulmonary surfactant, specifically bovine lipid extract surfactant suspension, using less invasive surfactant administration (LISA) technique or minimally invasive surfactant therapy (MIST) for rescue treatment of infants with Neonatal Respiratory Distress Syndrome.

BLEScath® supports the LISA method of surfactant administration. The administration of surfactant via a thin catheter compared with an ETT is associated with a reduced risk of death or BPD1.

LISA may offer institutions cost savings by decreasing the need for ventilation, consumables, diagnostic procedures, and investigations6.


BLES®, LISA and BLEScath®, are three innovations that are fast and may impact NRDS Treatment3,4,6,7.

  • The LISA method uses a small diameter catheter inserted into the trachea to deliver exogenous pulmonary surfactant to a spontaneously breathing patient supported by continuous positive airway pressure (nCPAP) to avoid intubation. LISA is intended for neonates ≥ 28 weeks gestation and/or ≥ 1000 grams.
  • LISA reduces the necessity for intubation and mechanical ventilation9.
  • LISA’s smaller catheter allows the flow of gas through the vocal cords while maintaining the physiological function of the larynx6.
  • LISA provides the advantage of postnatal circulatory adaptation under spontaneous breathing which may result in lower rates of intracranial hemorrhage (ICH)6.
  • Meta-analyses have shown that LISA is superior to nCPAP alone or the InSurE technique in terms of avoidance of bronchopulmonary dysplasia (BPD) and ICH6.
  • With LISA, long-term follow-ups report better pulmonary function and neurocognitive outcomes6.

Pivotal Benefits

BLEScath® is designed explicitly for use with BLES®

BLEScath® is designed explicitly for bovine lipid extract surfactant administration. BLES® has a very low viscosity formulation and has been tested to pass through the holes in the stylet’s anchor at the proximal end of BLEScath®. Other surfactants have not been tested with BLEScath®4.

The first of its kind. Integrated SS stylet is anchored and remains fixed in place.
The stylet does not require removal for surfactant instillation. The stainless steel stylet keeps its desired shape and does not migrate during the procedure9.
User-friendly, intratracheal insertion catheter without Magill forceps.
BLEScath® is a user-friendly device for healthcare practitioners who are not familiar with intubation or the use of Magill forceps6.
Markings: 7, 8, 9, 10, 11 cm determines the definite "Tip to Lip" distance based on weight (kg) calculation.
The Tip to Lip distance markers: 7, 8, 9, 10, 11 cm indicate the distance from the distal tip of the catheter to the patient’s lip, supporting proper catheter depth placement. The depth of insertion is 6 cm plus birthweight in kilograms4.
For example: The depth of insertion for a 1 kg baby is 6 cm + 1 = 7 cm.
BLEScath® supports BLES® instillation in supine positioning.
BLEScath® supports BLES® instillation in supine positioning. Based on literature reviews, more homogeneous surfactant dispersion is achieved with supine positioning8.
The SS stylet allows the catheter to be bent into the user’s preferred shape, such as gently curved* or hockey stick*.
*Click To Enlarge
BLEScath®'s patented, fixed, flexible stainless steel stylet provides healthcare practitioners with a customizable curvature preference such as gently curved or hockey stick may enhance the procedural speed and success of oral insertion9.
Stainless steel (SS) stylet is rigid yet flexible for ease of insertion.
BLEScath® improves the visualization of the vocal cords for catheter placement by eliminating obstruction in the trachea due to forceps9.
Distal tip markings; 2, 2.5, 3.5 cm aid in determining the catheter insertion depth at the vocal cords.
The distal markings of 2, 2.5, 3.5 cm and a single hole design decrease unilateral surfactant disposition, which may help facilitate the surfactant penetration distally for more rapid spreading and may reduce reflux7.
Thin diameter 5Fr catheter maintains physiologic pharyngeal function.
The thin diameter 5 Fr (1.67mm) of BLEScath® helps maintain6 physiologic pharyngeal function and spontaneous breathing, both essential factors for successful LISA technique4.
Soft, rounded distal tip may reduce tissue trauma during insertion.
BLEScath®'s soft, rounded, distal tip may reduce tracheal tissue injury commonly associated with straight, stiff, or minimally curved catheters4,6.
